Answer: 20 fragments
Explanation:
This particular restriction enzyme has a 4 bp (base pair) recognition sequence therefore it will cleave once every 4ⁿ bases where n indicates the number pf bases in the recognition sequence.
- The recognition sequence is 4 bp therefore this restriction enzyme cleaves once every 4⁴ = 256 bases. This is the length of the restriction fragment.
- Calculate the number of fragments by dividing the total number of bases ( where you assume equal frequency of bases ie. A+T = C+G) by the length of the restriction base.
- therefore 5000bp/256bp = <u>19,53</u> now this number ca n be rounded up to 20.
- The expected number of fragments on the electrophoresis gel will be 20 fragments.
Answer: The invention of the powerful atomic force microscope has enabled scientists to study cells at an atomic level. This enables scientists to scrutinize viruses at their atomic level and influence them for delivery of innovative treatments

The correct answer is immunoglobulins.
Immunoglobulins, also called as antibodies, refer to the molecules or glycoproteins generated by the white blood cells (plasma cells). They function as an essential component of the immune reaction by uniquely determining and combining with the specific antigens, like viruses or bacteria, and helps in destructing them.
